Isihloko mayelana nekhodi yombala ye-Resistor
I -resistor ingenye yezingxenye zesekethe kagesi esebenza ukulawula inani lemisinga kagesi. Ngokuvamile, kunezinhlobo ezimbili zama-resistor, okungukuthi ama-resistors e-wire coil kanye nama-resistors e-carbon. Ama-resistors e-wire roll avame ukusetshenziswa elabhorethri, enziwe ngokugoqa intambo encane ebusweni beshubhu ye-insulator. Ama-resistors e-carbon avame ukusetshenziswa kumasekethe kagesi, ayi-cylindrical, futhi anezintambo kuzo zombili izinhlangothi. Inani lokumelana ne-carbon resistor livezwa ngekhodi yombala futhi liboniswe ebusweni be-resistor.
Inani lokumelana le-resistor lingaziwa ngokuhumusha ikhodi yombala we-resistor. Ukuze uqonde lokhu, qala ubheke ithebula elilandelayo, bese ufunda inkinga yesibonelo ukuze uthole inani lokumelana ne-resistor.

Inani lokumelana ne-resistor esithombeni lingu…
Isixazululo:
Imibala emibili yokuqala imelela izinombolo ezimbili zokuqala zenani lokumelana, umbala wesithathu umelela amandla eshumi asetshenziswa ukuphindaphinda, kanti umbala wesine umelela ukubekezelela ukuphambuka.
Umbala wokuqala = obomvu = 2
Umbala wesibili = i-orenji = 3
Umbala wesithathu = onsundu = 101 = 10
Umbala wesine = igolide = 5%
Inani le-resistor lingu-230 Ω ngokuphambuka okungu-5% x 230 Ω = 11.5 Ω. Uma kukhona ushintsho ekushiseni, ukumelana okuncane kungu-230 11 – 11.5 Ω = 218.5 Ω kanti ukumelana okuphezulu kungu-230 Ω + 11.5 Ω = 241.5 Ω.
Inkinga yesampula 2:
Iyini inani lokumelana ne-resistor esithombeni?
Isixazululo:
Umbala wokuqala = onsundu = 1
Umbala wesibili = omnyama = 0
Umbala wesithathu = okwesibhakabhaka = 10 6 = 1000,000
Umbala wesine = igolide = 5%
Inani le-resistor lingu-10,000,000 ,000 ngokuphambuka okungu-5% x 10,000,000 Ω = 500,000 Ω. Uma kukhona ushintsho ekushiseni, isithiyo esincane ngu-10,000,000 500 – 500,000 Ω = 9,500,000 Ω kanti isithiyo esiphezulu ngu-10,000,000 Ω + 500,000 Ω = 10,500,000 Ω.
